It is surrounded by nine outer dense fibres, which are not found in other cilia. In the middle piece (about 5 µm long), the axonema and dense fibres are surrounded by a sheath of mitochondria. The middle piece is terminated by a dense ring, the annulus. The principal piece is about 45 µm long. It contains a fibrous sheath, which consists of dorsal and ventral longitudinal columns interconnected by regularly spaced circumferential hoops. The fibrous sheath and the dense fibres do not extend to the tip of the tail. Along the last part (5 µm) of the tail, called the end piece, the axonema is only surrounded by a small amount of cytoplasm and the plasma membrane. | ||

Objectives
- Gain an overview of the microanatomy of the male reproductive system.
- Undertake a microscopical examination of the testis, epididymis, vas deferens, seminal vesicle, prostate gland, penis, and sperm. The functional significance of the various histological structures identified will be discussed.

Terms
- cortex - (Latin = rind, or bark) outer layer of an organ.
- hilum - or hilus (Latin,= a trifle; depression in a seed) a depression at vascular entrance/exit of a gland or organ.
- medulla - (Latin, medulla = pith, marrow) the inner portion of an organ, in contrast to cortex.
- mucosa - (Latin, = mucous membrane) thin layer which lines body cavities and passages formed by epithelium and lamina propria.
- parenchyma - (Greek," + enkeim = to pour in) the essential functional cells of an organ as opposed to its stroma.
- serosa - (Latin, serum = whey; a pale fluid) a serous membrane lining body cavities.
- stroma - (Greek, = a cover, table-cloth, bedding) term for the internal supporting frame-work of a tissue, or organ, as opposed to its parenchyma.
- tunica albuginea - a dense, white, fibrous sheath enclosing a part or organ.
